Given below are two statements: Statement I: Competitive release occurs when a species, whose distribution is restricted to a small geographical area because of the presence of a competitively superior species, expands its distributional range dramatically when the competing species is experimentally removed. Statement II: In Connell's field experiments on the rocky sea coasts of Scotland, the larger and competitivel
Options
- AStatement I is false but Statement II is true.
- BStatement I is true but Statement II is false.
- CBoth Statement I and Statement II are false.
- DBoth Statement I and Statement II are true.
Correct answer
B. Statement I is true but Statement II is false.
Step-by-step solution
Statement I correctly defines competitive release. A species whose distribution is restricted to a small geographical area because of the presence of a competitively superior species expands its distributional range dramatically when the competing species is experimentally removed. Statement II is incorrect because in Connell's field experiments on the rocky sea coasts of Scotland, the larger and competitively superior barnacle is Balanus , which dominates the intertidal area and excludes the smaller barnacle Chtha
